Ooops....
Alphas always have homogenous processors, so they just have a line which
says:
cpus detected : #
Unfortunately this isn't the number of CPUs detected but rather the CPU
slots which are filled, so you need to count the number of numbers after
the colon in that line.
PPC seems to use the x86 style, and on sparc you need to count the number
of lines which begin `CPU#:' and end with `online'.
Aren't consistent interfaces marvellous.
Sorry for misleading you all earlier.
I can't check anything but x86 directly, so if any of this has changed, we
can assume the format of /proc/cpuinfo has probably changed and thus we
can't reliably parse it.
